IMPROVEMENT IN PAPER-FILES.

Specification forming part of Letters Patent No. 113,991, dated April:25, 1871.

To all whom tias may concern:

Be it known that I, GEORGE W. EMERSON, of Chicago, in the county of Cookand State ot' Illinois, have invented a new and useful Improvement inPaper-Clips; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing and letters marked thereon, in which- Figure l is aperspective representation ot' a paper-clip with my device arranged tohold the fasteners in place. Fig. 2 shows one form of my spring-support;Fig. 4, the ordinary fastener; Fig. 3, another form of the support 5 andFig. 5 shows the support in perspective.

The nature otl the present invention consists in attaching to the bodyof the clip slotted spring-sulviports, for holding the binders inposition when paper is being put thereon, as hereinafter fullydescribed.

A represents the pad, B C D the bar, and E the spring, of a clip now inuse. N0 nov elty, therefore, in their regard is claimed.

F represents a sheet-metal spring-support, which is bent at right anglesto conform to the inside of the body B C of the clip, and fastened to itat G G'by rivets or other suitable device; and its lower central part isprovided with a slot, L L, so that when fasteners of differentthicknesses are used each respective fastener may have the properpressure upon it to hold it in position to pierce the paper.

The lower end of the support is provided with slots, I to receive thefasteners or binders J 5 and the tips of the support are turned a littleupward, for convenience of placing the binders in position, as shown inFigs. l and 2- H, Figs. 1 and 3, represents what I consider anequivalent-support, with the exception that the lower part is notslotted. It, however, holds the binders in place by means ofspringpressure. It is not bent at right angles, but passes through thebody B ot` the clip and fastens, as shown in Fig. 3, to the pad A, backof the said body.

In manufacturing the supports I find that rolled brass answers thepurpose well, and is cheaper than steel, as less labor is required inits use, the thickness shown in the drawing being about the kind ofplate required.

In the drawing it will be seen that the spring E is designed to forcethe bar D down, and thus cause the binders .I to pass through the paperbeing bound; but it is not necessary that this arrangement be alwaysused with my spring-supports, inasmuch as any suitable bar would answerthe same purpose as D.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, ls-l- One or more spring-supports, F l, slightlyrounded, as described, attached to a paperclip, and arranged to hold thebinders J in position to pierce paper, as herein described and shown.
